The Smart Battery Case looks like the one the company launched some years ago for the iPhone 6 and the iPhone 6s, but with a few key improvements.
How It Works With The New iPhones
The case includes a built-in battery, which extends the battery life of the phone inside. The case plugs into the Lightning connector of the iPhone and perpetually keeps it charged until the battery in the case drains completely.
The case can then be charged either through the Lightning connector on the bottom or wirelessly. The case supports Qi charging so you can have the phone inside this case and it will still charge wirelessly. The case also supports fast charging via USB-PD chargers.
Aside that, there are several other design improvements over the older Smart Battery Case. The battery portion in the back now goes all the way to the bottom edge instead of just sticking out in the middle, which makes it look a lot better. The new case also does not have a giant lip on the front, and it has a uniform border around all sides.
The case has a soft silicone finish on the exterior and microfiber lining on the interior. It’s only available in two colors, black and white, for all three phone models.
In case of the XS and XS Max, you really don’t see much of your phone at all once you put it in the case but the XR case does show a bit of the phone’s color through the camera opening on the back.
The Smart Battery Case is priced at $129 for all models.
